HULL STRUCTURE OF' SHIPS AND THE LIKE Filed ug. 21, 1929 2 sheets-sheet2 Haro/d du/arid Esce/9m Cam/as I Patented Jan. 31, 1933 'rss HAROLDEDWARD rosonLYN cA'ivirs', or LoNDoN, ENGLAND HULL STRUCTURE OF SHIPSVAND THE LIKE Application filed August 21, 1929, Serial No. 387,323, andin Great Britain August 28, 1928.

An application has been filed in Great Britain, August 2S, 1928. Thisinvention relates to improvements in hull structures of ships and thelike and has for one of its objects the provision of a closed Y inaccommodation alley way throughout substantially the length of thevessel.

A further object of the invention is to accommodate in the constructionthe various steam, water, electrical and mechanical services in such away that more convenient inspection and utilization can be eected thanis possible with known arrangements.

Another object of the invention is the provision of means whereby thecargo holds may be more effectively ventilated than has been possiblewith known structures, and whereby access can be had to the doublebottom of the vessel at all times in each hold whether laden or unladenthus enabling drainage water to be removed with greater certainty thanhas been possible heretofore.

in additional object of the invention is the provision of means wherebyincreased longitudinal strength may be obtained compared with that ofknown structures on a weight of material per ton dead weight basis.

The invention consists in the arrangement of a closed in accommodationalley Way on and above the upper deck of a ships hull structure, saidalley way extending for the greater part of the length of said structureso as to enable access to be had from one end of the ship to the other,said alley way in some cases communicating with the bottom of the vesselunder each hold by means of vertical trunk ways.

1n the drawings Figure l diagrammatically illustrates the application ofa closed in accommodation alley way in accordance with this invention toa Hush deck vessel having a forecastle at the forward end and a steeringengine house at the after end;

Figure 2 is a plan of the vessel illustrated in Figure l; and

Figure 3 is a cross sectional view of Figure l.

As illustrated in Figures 1 and 2 the alley way structure comprises aforward section a,

an engine and boiler room casing ,25` and an after section c thethreeparts being connected in any well known manner in order, that thestresses in the several parts a b and c are transmitted from one part tothe others in an 55 adequate manner. y l The alley way structure a b 0is arranged onland above the upper deck of the hull structure (seeFigure 3) and accommodates steam pipes, water pipesyelectric Wires,steer- 60 ing lrods and other gear in such manner as toenable readyinspection thereof and rapid repairs thereto to be effected. The afterend of the part c of the lalley Way terminates in the steering enginehouse diwhilsttheffor- 65 ward end. ofthe parta of said-'alley wayterminates in the forecastle e, the closed in accommodation alley Way abc enabling accessjto be had from one end of the vessel lto .the otherand to the sounding pipes ofthe various holds, said alley way alsoreceiving lthe air pipes from the double bottom. f ,E Iii-some instancesthe alley way or parts thereof may' be included `in the system lofventilationvof the cargo holds inasmuch as the said alley wayY or partsthereof may act as a. duct orV ducts for the transmission of air to orfrom the various compartments.

In the case of a vessel constructedwith a poop, 'bridge andfo'recastlethe alley way comprises two sections one located between the bridge andthey forecastle and the other between the bridge and the poop, the twosections 4being associated withthe bridge structure-in such a mannerthat continuity of strength of the structure is maintained.

The longitudinal alley Way a b c may be connected with the double bottomby one or more vertical trunk waysg j@ i j c through whichaccess can behad to the" bottom of the vessel under each hold at alltimes even whensaidholds are filled with cargo. The fbot.- Y Y tom of each of the trunkways g h z' j mnay terminate' in a well Zin which drainage water fromthe holds will collect and from which it can be pumped in the ordinaryway. i

As illustratedA in Figure 8, the drainage `arrangement comprises aVscupper ppem draining into the ,Well Zand a suctionpipe frQle,engineroom for pumping the drainage Water' out of said Well Z. Asillustrated 'in Figure 3 the Well Z extends the full Width of the vesselbut in some cases the said Well is only arranged in the centre portionof the vessel under a Vertical trunk Way in which case the piping mustbe rearranged. l

. Each vertical trunk Way rmay be provided With a manhole 0 at the upperpartarrang'ed to enable access to be had to said vertical trunk Way fromthe'longitudinal alley Way and manholes pp at the lower part of saidtrunk Way in order that access can be had to the Well Z. To enableaccessV to be had to other parts of the double bottomV the trans- Versefloors r may be provided With manholes g. VObviously if manholes suchasok are ob-` jectionable in the longitudinal alley Way' thenisuc'hmanholes may be replaced by small hatches.' l

I claim f yl. Afships hull structure comprising a f 'closed inaccommodation alley Way arranged 'on and above the upper deck of thestructure, Y

said alley Way extending for the greater part of the length or" saidstructure so as to enable access to be had from one end of the ship tothe other including Vertical trunk Ways arranged to enable communicationbetween the alley Way and the bottom of the vessel under each hold to beveected Without disturbance of the-cargo `in the holds, substantially asdescribed. v v

2. A ships hull structure vcomprising 'a closed in accommodation alleyWay arranged on and 'above'theupper deck of the structure, said alleyWay extending forfthe greater` part 'of the length of said structure soas to enable access to be had 'from one end of the `ship to the other,said longitudinally disposed .alley Way being arranged in sections andconnected f 1 to the bridge, the engine and boiler room cas'- ing or thelike so as to 'stiien the hull structure as la Whole and 'enablecommunication to be established throughout substantially the length ofthe vessel, substantially as described.

3. A ships hull structure comprising 'a closed in accommodation alleyWay arranged on and above the upper deck of the structure,

said alley way extending for the greater part y ofthe length of saidstructure soV as to enable V access to be vhad from oneend of the shipto the other, said longitudinally disposed alley Way being arranged insections and connected to the bridge, the engine and boiler roomcasingfor the like so as to stiffen the hull structure as a Whole andenable communication lto be established throughoutv substantially thelength of the lVessel andfverti'calftrunk Ways connected to said alleyWaysections to Venable communication between the alley Way andthe bottomofthe vessel to be effected Without disturbance ofthe cargo* intheholds,

substantially Aas described. 1 y Y. Y 'H. E. J. CAMPS.
